feat: one page for a category, tag, budget or merchant

The page answers how much and whether that is normal: this month per
currency with count, median and pace against a typical month, thirteen
months as lanes per currency, and what is inside (merchants, cards,
budgets, tags, subtags) on 1 to 4 with Enter narrowing the transactions
below. Budgets keep spent, left and overspent with the limit line;
expense and revenue accounts use the same page with visits and cadence.
The twelve period cards and per-day charts are gone.
